COMBINED INSOLE AND SHANK Filed July 7, i932 Patented ug. 8, 1933 UNITED STATES PATENT 2 Claims.

, taken in connection with the accompanying drawing wherein:

Figure l is a perspective View of the combined inner sole and shank reinforcement with a portion of the insole back to show the combined cushioning and Ventilating features of the invention.

Figure 2 is a plan View of the shoe inner sole. Figure 8 is a transverse sectional View therethrough and Figure 4 is a side edge elevational view thereof.`

Referring more in detail to the drawing it will be seen that my improved inner sole, designated generally by the reference character 5, may be made of leather or other eXible material, and is designed to conform with the shape of the interior of the shoe to which it is applied, and in the present instance the insole is of the shape of the interior of a ladys shoe. On its top side or face the insole 5 is covered in the customary manner with a thin strip 6 of leather or other suitable material known as a sock-lining, conforming in shape to the shape of the sole 5 and glued or otherwise secured or united therewith.

To the under face of the insole 5 there is secured by stitching 7 a shank reinforcement 8, which is made of bre paper or other suitable material.

Inserted between the shank reinforcement 8 and the inner sole 5 is a cushion in the nature of a rubber tube 9 open at its ends, and the inner sole 5, at the shank thereof is buffed or grooved out so as to provide a seat or pocket 5a for the tube 9. At either or both ends of the pocket 5a the inner sole is provided with eyelets 10 opening through the sock-lining 6 and forming air ports for the pocket 5a, the eyelets being arranged adjacent the open ends of the tube 9. In the region of the pocket 5a the insole 5 is thinned down, so that the softening effect of the tube beneath is readily apparent to the wearer of the shoe.

The insole with which the present invention is concerned is provided with the usual metal strip 12 and it will be seen that the tube 9 is so positioned relative ot this strip 12 as to serve as a soft cushion support for the foot at the instep thereof, thus cushioning the effect of the usual metal strip l2 and thereby adding to the comfort of the wearer.

lt Wiil be also apparent that when the shoe in which the insole is arranged is worn, suction caused by the rising of the wearers foot during walking will draw or suck air into the tube the air entering the pocket 5a through the eyelets lo, and when the foot is depressed the air thus drawn in will be discharged'or forced from the 65 tube through said eyelets thereby causing aciroulation of air which will serve to ventilate the shoe, cool the foot, and at the saine time prevent coiiapse of the tube 9.

Even though have herein shown and de- 7o scribed the preferred embodiment of the invention, it is to be understood that the same is susceptible of further changes, modifications and improvements coming within the scope of the appended claims.

Having thus described my invention, what l claim as new is:

l. As a new article of manufacture, a shoe insole, a shank reinforcement united therewith, said insole having a portion thereof thinned down 8o and grooved and providing with said shank reinforcement, a closed pocket, an open ended tubular cushioning element vwholly conned within said pocket; said insole having an opening in the region of said pocket.

2. In combination, a shoe inner sole, a socklining covering the topface of the inner sole, a shank reinforcement united by stitching to the under side of said inner sole, a flexible tube conlined between said inner sole and shank rein- 90 forcement, said tube being open at its ends, and an eyeletl at one end of said tube opening through the inner sole and sock lining so as to permita circulation of air to thereby maintain the tube from collapsing and also ventilate the foot. c
